IMPROVEMENT IN MACHINES FOR CUT-MARKING WARPS Specification forming part of Letters Patent No. 123,617, dated February 13, 1872.

To allpersons to whom these presents may come Be it known that I, ALEXANDER M. DAMON,

. of Lowell, of the county of Middlesex and State of Massachusetts, have made a new and useful Machine for Gut-Marking Warps; and do hereby deolare'the same to be fully described in the following specification and represented in the accompanying drawing.

Heretofore in slashers and warp-sizing machines it has been customary to arrange the cut-marking mechanism in advance of the dryin g cylinder or mechanism, whereby the warps, after having been subjected to the action of the latter or dried, were cut-marked or printed. As a consequence the mark or marks are or were liable to be defaced or spread upon the warps or other layers of the warps not so printed to the injury thereof.

In carrying out my invention in part, I arrange the cut-marking mechanism in rear of the drying apparatus, so that the warps may be printed or cut-marked before being subjected to the action of the said drying element or mechanism of the slasher or sizing-machine, and thus I cause the print 'or prints made by the cut-marking mechanism to be subjected, with the sizing of the warps, to the action of the drying cylinder or apparatus, whereby such mark or marks will be dried, with the sizing of warps, before being wound on the loom-beaman advantage which will be readily seen and appreciated by manufacturers. In further carrying out my invention, I have produceda new or improved apparatus for cut-marking the warps.

Of the drawing, Figure 1 denotes a top view of partof the frame of a slasher, with the drying-cylinder and my new or improved cut-- marking mechanism disposed in rear of such cylinder, or in the position between such and the sizing apparatus, so that the warp in passing fi'om the sizing apparatus to the dryingcylinder will bemarked before being sized. Fig. 2 is a top view, and Fig. 3 a vertical and longitudinal section, and Fig. 4 an inner-side view of the cut-marking mechanismpmamene In th aid drawing, A denotes part of the frame of a slasher; B, the drying-cylinder; and G, a roller for supporting the warps in their passage from the drying-cylinder to the loombeam. In rear of the said roller 0 and dryingcylinder is an ink reservoir or trough, D, and a printing or marking lever, E, whose ful'orum or pivot is shown at F. The trough and mark- I ing portion a of the lever are to extend underneath the warpsin their passage to the dryingcylinder. To the shorter arm b of the marking-lever E an end of a slide-rod, G, is pivoted or jointed, such rod being supported or applied to the frame A, so as to be capable of sliding longitudinally. At or near its opposite end the rod is bent upward at a right angle, as shown, and against a cammed tube or' sleeve, H, so applied to a horizontal shaft, I, as to turn with or be revolved by it, and be capable of sliding lengthwise on it. Enveloping the said shaft is a helical spring, 0, which, arranged in the sleeve, is to be so applied to it and the shaft as to drive the sleeve forward, when the outer extreme of its cam may pass a stud, (1, extended from the frame A, in manner as shown. The advanced end of the sleeve has a helical cam, 0, formed on it. There is also a stud or tooth, f, extended from the sleeve at or near its middle, as represented, and in range with the straight part or fall g of the cam 0. Furthermore, the shaft I, supported in bearings h h, carries a worm-gear, i, which engages'with a screw or worm, k, fixed on the shaft Z of the roller 0.

The warps, during their passage over the roller 0, revolve it, whereby, by means of the worm and worm-gear, the shaft I will be steadily revolved, and will carry the sleeve around with it. As the sleeve may revolve, it will be forced backward on the shaft by the action of the helical cam e and the stud 61 until the extreme advanced point of the cam may pass by the stud. When this takes place, the tooth f at the middle of the sleeve will have been brought around directly in rear of the vertical part of the slide-rod G. .As soon as the extreme outer end of the cam 0 may have passed the stud d, the spring within the sleeve, hav-. ing been contracted during the revolution of the sleeve, will suddenly advance the sleeve on the shaft until the cam, near its rear terminus, may have brought up against the said stop d. This sudden advance of the sleeve" will cause the marking-lever and cause it to rise out of the inking-trough and against the warps in such manner as to apply ink or color thereto. The moment the tooth 0f the sleeve may have revolved clear of the slide-rod, the markinglever will fall back into the trough and upon its bottom. The ink or coloring-liquid used in such trough is to he suffered to stand at a level above the upper surface of that part of the marking-lever which performs the printing of the warps.

toothed and cammed sleeve H, its operative spring a, the shaft I, the worm-gear a, and the worm k, all being arranged and applied to the frame A and the supporting-roller G substantially as specified.

2. Ialso claim the new or improved arrangement of the cut-marking mechanism relatively to the drying cylinder or mechanism, viz., in rear of such, so as to print or cut-mark the warps before they may be subjected to such cylinder or drying mechanism, and in order that the cut mark or marks may be dried by the action of such cylinder or drying mechanism while it may be operating to effect the desiccation of the sizing of the warps.
